Ondemand recording up to 5 calls in this same time

HI,
Is it possible to have on demand recording up to 5 calls in this same time?
If yes what way can i achieve this. I know with freepbx this is a problem.

Thanks

Asterisk can record a lot more than 5 calls at a time. If you explained the FreePBX problem it might be easier to understand what your real problem is.
